My invention relates generally to railway car structure, andspecifically to a form of metallic car end which is designed for use onbox cars, either as a portion of the original car structure, or as arepair partwhich may be substituted in cars whose ends have beendamaged.

The general purposes of my invention are, to provide a form of a car endstructure which may be economically manufactured and repaired at littleexpense; which is strong and stable so as to effectively resist thevarious stresses to which such a part is sub ect, lncluding variousblows and stresses imparted by shifting load, weaving influences,vertical stresses incident to supporting the roof, and all the othervarious stresses received by the end structure in service. 7 Theaccompanying drawings are illustrative of one form of my invention,Figure 1 being an elevation; Fig. 2 showing a vertical section takenapproximately on line 22 of Fig. 1; and Fig. 3 a detail illustrating afront portion of a modified form. Fig. 4 is a detail of a side portionof same.

It has been customary in practice to form car ends of sheet metalsections which are joined at their edges, the joints between thesections sometimes running horizontally and sometimes vertically of thestructure. Such end structures have been corrugated or ribbed in variousfashions for the purpose of imparting additional stiffness and stabilityto the metal. One of'the serious considerations in such structures hasbeen the provision of sufficient strength and stability at the jointsWhere the adjacent sections are riveted together, as such joints areusually disposed, as a matter of convenience in manufacture, at pointsWhere they are likely to be subjected to severe stresses due to shiftingload or other internal or external infinence. v

In the structure illustrated in the accompanying drawings, I havedevised an end structure having the various sections or portions ofmetal of which it is composed so ribbed, arranged, and secured as toprovide a maximum strength and stability at the joints, and a car endhaving great strength and stiffness for its weight. a

In the form illustrated, it will be see] that the end is made up of afirst section 1,

a second section 2, and an intermediate section 3. The first and secondsections are provided with suitable stiffening ribs or corrugations 4which may run vertically as shown, or may be otherwise disposed so as toimpart stiffness to the structure. Adjacent its lower edge, the firstsection 1 has pressed therein. a stiffening rib or corrugation 5extending the entire length of the section and adapted to cooperate withthe oppositely disposed frame members of the car to which the endstructure is affixed. The margins 1 of the section may be suitablyflanged to provide portions for attachment to the proper members of thecar framing. The

portion of the section adjacent the stiffening corrugation 5 may beslightly offset to accommodate the upper portion 3 of the middle section3. The middle section 3 is formed with a longitudinal corrugation orstiffening rib 6 disposed in proximity to one of its margins, leavingthe portion 3 of sufficient extent to extend behind the corrugation 5 ofthe first section, to which first section the middle section 8 isattachedby rivets 7 or other suitable fastenings disposed at the inwardside of the stiffening corrugation 5. When in position, the rib (3 ofthe middle section lies adjacent the mar gin of the first section,running substan- .tially parallel to the rib 5, and forming an ployed tosecure the outer margin of the intern'icdiate section to the secondsection.

By virtue of this arrangement, it will be seen that I have a very rigidand stable reinforcing member formed by the lapped portions of thesections, the corrugations 5 and 6 cooperating with the underlyingportions of the sections 3 and 2 to form box girders which extendcontinuously between the framing members of the car to which thesections are attached. Furthermore, I have the triple. thickness ofmetal disposed intermediate the corrugations 5 and 6. When the jointsare horizontal, as illustrated, this arrangement provides a water-proofstructure, inasmuch as all of the exterior joints open downwardly, thuseffectively preventing the ingress of water and dust. The underlappingarrangement of the sections also gives the end structure a plaininterior surface.

If desired, as illustrated in Fig. 3, the extremities of the section 3may be extended to form the attaching flanges 10 by which the end may besecurely tied into the car structure. If desired, the corrugation 6 maybe extended around the corner to afford additional stability at thecorners and to strengthen the flanges 10.

In the form illustrated, the arrangement provides a very strong girthmember which extends across the end structure approximately at itsmedian line, and is very effective in resisting stresses which wouldtend to distort or damage the end. It is obvious, however, that ifdesired, the joints may be disposed verticallv, in which case thestiffening member formed by the conjoined corrugated edges of thesections acts both as a central stlfiening member in the end structureand a roof supporting member. The corrugations 4 extending from adjacentthe median stiffening member to adjacent margins of the sections whichare attached to frame parts, operate to strengthen and stiffen theentire end structure and to transmit stresses received by its variousparts to the median stiffening member and the frame members.

In practice, this end may be economically manufactured as comparativelysmall sheets are required to make the sections, and the structure may bereadily and economically repaired, as a damaged section may be removedand replaced without necessitating the removal of undamaged sections.

I am aware that the structure is capable of various changes andmodifications not herein illustrated and described, without departingfrom the spirit and scope of the invention.

What I claim is:

1. A car end composed of three conjoined.

sheet metal sections the form and arrangeedges of the third section.

3. A car end structure including three sheet metal sections overlappedseriatim and secured together, the exterior overlapped portions of saidsections being corrugated to form substantially parallel strengtheningmembers disposed adjacent a junction line of said sections.

4. In a car end, three sheet metal sections.

the middle one of which has a portion ex tending behind a corrugatedportion of the section at one side thereof and a corrugated portionoverlapping the section at the other side thereof, and fastening meanssecuring each of the sections to both the others intermediate saidcorrugated portions.

5. In a car end, the combination of a first section of sheet metalformed with a corrugation extending longitudinally adjacent an edgethereof, an intermediate section hav ng a portion overlapping the saidcorrugation and secured to the first section at the inner side of saidcorrugation, said intermediate section being formed with a corrugationextending longitudinally adjacent the edge of the first section, and athird section having a portion overlapping the corrugated portion of theintermediate section and secured to said intermediate section at bothsides of the corrugation therein.

6. In a car end, a plurality of conjoined sheet metal sections, eachoverlapped upon the others, said sections being shaped to form aplurality of substantially parallel box girder members extending alongthe joined edges of the sections.

7. In a car end, a plurality of sheet metal sections including anintermediate section secured to a section at one side thereof by adouble line of fastenings and to a section at the other side, thereof bya double line of fastenings, the sections being corrugated between thelines of fastenings, and each overlapping both of the others.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses, this 17th day of I ebruary, 1915.
